Dirty old towns

A diary item earlier this week noting that Amicus has installed filtering software for its internet forums that renders Scunthorpe as S****horpe and Blackpool as Black***l elicited a flood of readers' suggestions, from as far afield as Cockermouth (Cumbria) and Climax (Missouri). Over to you now for your suggestions.

It all started with a diary item earlier this week noting that the trade union Amicus had installed filtering software for its internet forums to detect and repress any words or letter combinations deemed offensive. This had the unfortunate consequence of neutering several entirely innocent British placenames, rendering Blackpool as Black***l and Scunthorpe as S****horpe.

I should of course have guessed, but the item produced quite the largest postbag of my tenure as Guardian Diary editor. Am I right in suspecting there is a schoolboy streak in Guardian readers that is sadly under-catered for? In any event, among the fine placenames submitted yesterday by readers as likely to trigger Amicus's fiendishly efficient filtering software are Penistone (Yorkshire), Fugit (Kentucky), Titlis (Switzerland) and Muff (County Donegal).

This morning's postbag brings the Orkneys hamlet of Twatt and a road junction outside Essendon in Hertfordshire where, we are assured, Cucumber Lane meets Cum Cum Hill. We are further alerted by a motorcycling reader to the existence of a small town in Kentucky by the name of Big Bone, succeeded a mere five miles up the road by Beaverlick.
